*650 alpha on the AP.
I also got one in a lootbox. Can concur that it is actually quite fun to play as it is quite a meme of a tank, but yes, it is absolutely broken and toxic for the game.
I actually quite like playing it with AP mostly, because the low penetration absolutely forces you to think very carefully about shots due to the low DPM, but at the same time, the large calibre of the gun means there are many overmatch opportunities if you know your tanks. 220ish pen HESH also feels super unreliable except against rears and absolute paper targets for me, especially against sides
